I know that as velocity approaches the speed of light the time dilation shoots to infinity as shown below. enter image description here

1)So I want to know how time is perceived from the point of view of the photon?

2)Since time stops at the speed of light how do photons move?

3)Is this why photons do not decay or are made up of any smaller particles?

  1. Photons are absorbed at the same moment they are emitted (as seen from the point of view of the photon.)
  2. If you think of things conversely, it is only a massless particle that can experience no lapse of time. The photon is only able to move at c because it is not moving at all in time.
  3. I believe the answer to this question is unrelated.
